A high-contrast pen and ink portrait of a young woman with a soulful gaze, based on a delicate pencil sketch. The style features intricate cross-hatching and fine-line stippling to create depth and shadow. Her hair is styled in a loose, messy bun with wispy, flyaway strands framing her face. The linework should be sharp and precise, mimicking a technical drawing pen on textured paper. Deep, dense ink shadows contrast against bright highlights on her skin, emphasizing her sharp cheekbones and expressive eyes. Minimalist background with subtle ink splatters and hatching.
